Low Pressure Structural Molding

Horizon Plastics International is a leader in structural foam/structural web manufacturing processes. Established in 1972, Horizon Plastics services both industry giants and small entrepreneurs. Products produced by Horizon Plastics include children’s toys, building products, industrial components and environmental products, to name a few.

Horizon produces plastic parts using two low pressure injection molding processes, Structural Foam and Structural Web. Plastic parts made using the Structural Foam technology have a cellular or structural core, surrounded by dense outer skins which combine to give the parts a high strength to weight ratio and up to twice the rigidity of solid parts of the same weight and material. Structural Web molding is a low pressure injection process used to produce plastic parts where hollow cross sections, varying wall thicknesses, an improved cosmetic appearance, and a superior stiffness-to-weight ratio are important considerations for the final part design and functionality.

Horizon Plastics is headquartered in Cobourg, Ontario and has an additional manufacturing location in Mexico.
